A moving account of one man's race to save a herd of elephants – with unforgettable characters and exotic wildlife, The Elephant Whisperer is an enthralling book that will appeal to animal lovers and adventurous souls everywhere.When South African conservationist Lawrence Anthony was asked to accept a herd of 'rogue' elephants on his Thula Thula game reserve in Zululand, his common sense told him to refuse. But he was the herd's last chance of survival – dangerous and unpredictable, they would be killed if Anthony wouldn't take them in.As Anthony risked his life to create a bond with the troubled elephants and persuade them to stay on his reserve, he came to realize what a special family they were, from the wise matriarch Nana, who guided the herd, to her warrior sister Frankie, always ready to see off any threat, and their children who fought so hard to survive.

Mechanical Engineering, an engineering discipline borne of the needs of the in­ dustrial revolution, is once again asked to do its substantial share in the call for industrial renewal. The general call is urgent as we face profound issues of pro­ ductivity and competitiveness that require engineering solutions, among others. The Mechanical Engineering Series features graduate texts and research mono­ graphs intended to address the need for information in contemporary areas of me­ chanical engineering. The series is conceived as a comprehensive one that covers a broad range of concentrations important to mechanical engineering graduate education and re­ search. We are fortunate to have a distinguished roster of consulting editors on the advisory board, each an expert in one of the areas of concentration. The names of the consulting editors are listed on the next page of this volume. The areas of concentration are applied mechanics, biomechanics, computational mechanics, dynamic systems and control, energetics, mechanics of materials, processing, ther­ mal science, and tribology. I am pleased to present this volume in the Series: Modern Inertial Technology: Navigation, Guidance, and Control, Second Edition, by Anthony Lawrence. The selection of this volume underscores again the interest of the Mechanical Engi­ neering series to provide our readers with topical monographs as well as graduate texts in a wide variety of fields.

Automatic navigation makes ocean-going and flying safer and less expensive: Safer because machines are tireless and always vigilant; inexpensive because it does not use human navigators who are, unavoidably, highly trained and thus expensive people. What is more, unmanned deep space travel would be impossible without automatic navigation. Navigation can be automated with the radio systems Loran, Omega, and the Global Positioning System (GPS) of earth satellites, but its most versatile form is completely self-contained and is called inertial navigation. It uses gyroscopes and accelerometers (inertial sensors) to measure the state of motion of the vehicle by noting changes in that state caused by accelerations. By knowing the vehicle''s starting position and noting the changes in its direction and speed, one can keep track of the vehicle''s present position. Mankind first used this technology in World War n, in guided weapons where cost was unimportant; only 20-30 years later did it become cheap enough to be used commercially. The electronics revolution, in which vacuum tubes were replaced by integrated circuits, has dramatically altered the field of inertial navigation. Early inertial systems used complex mechanical gimbal structures and mechanical gyroscopes with spinning wheels. The gimbals allowed the gyroscopes to stabilize a mass (called a "platform") so that it remained in a fixed attitude relative to a chosen coordinate frame, even as the vehicle turned around any or all of its three major axes.

Anthony Lawrence is one of Australia'smost highly-regarded poets and winner of twoof the country's most prestigious poetry prizes.He characteristically sets his poems withinpowerful landscapes and seascapes. There is adramatic confrontation in them, between theelemental forces of nature, and those withinthe consciousness of his characters. His focusis on relationships, the rhythms of work, andthe presence of danger in these primal settings.In an interview, Lawrence says of his work:"I'd like to think that a couple of my poemsachieve this tricky balance: landscape veinedwith humanity, flora, fauna, what's imaginedand what's experienced ... I write about natureto define my life."Strategies for Confronting Fear, a selectionfrom six of his nine published collections ofpoetry plus a body of new work, is Lawrence'sfirst volume of poetry to be published in theUK."Lawrence's work is accessible while stillretaining the integrity of a unique poeticvision."Australian Book ReviewANTHONY LAWRENCE was born in 1957 and left school at 16, working first as a jackeroo and then travelling for several years before returning to New South Wales to become a teacher and writer. While working as a fisherman in Western Australia, he secured a literary fellowship whichenabled him to devote time to writing poetry. He has won numerous awards for his poetry, including a Senior Fellowship from the Australia Council, one of the most prestigious funding awards a writer can be accorded in Australia.
